Problems solved by technology

[0003] However, in view of the increasingly frequent and violent car bomb incidents in the international community, the above-mentioned explosion-proof blankets cannot be applied in terms of explosion-proof specifications or explosion-proof lethality.
And because it is used for large explosives, it is also required to have excellent anti-knock performance and light weight, and the existing explosion-proof blankets cannot meet the above requirements

Embodiment 1

[0034] Such as figure 1 As shown, the car bomb explosion-proof fence has a width of at least 1.8m and a length of 20m; it is composed of 20 layers of high-strength, high-modulus ultra-high molecular weight polyethylene fiber non-weft composite materials, and adopts "Z" type overall sewing. Sewing machine for sewing. Each layer of the non-weft cloth composite material is composed of at least two layers of non-weft cloth orthogonally superimposed.

Embodiment 2

[0036] see figure 2 , image 3 , the car bomb explosion-proof fence width is at least 1.8m, and the length is 25m. The high-strength and high-modulus polyethylene fiber composite continuous roll with a width of 1.2m is used as the basic material, which is divided into two units with a total of 40 layers. The materials are arranged as shown in the figure: the first unit, the 10th floor is 0-degree direction, 1.8m wide, and 1.2m+0.6m composite sheet is used for sewing seams; the 10th floor is 90-degree direction, 1.2m wide×1.8 The m-long composite sheets are spliced ​​continuously. The second unit: the 10th floor is 0 degree direction, 1.8m wide, using 1.2m+0.6m composite sheet to sew the seam, the seam is in the opposite direction to the first unit seam; the 10th floor is 90 degree direction, using 1.2m Sheets of width × 1.8m length are spliced ​​continuously.

[0037] The above-mentioned 40-layer composite coil material superimposed adopts "Z" type integral sewing as a wh...

Embodiment 3

[0039] A method of using an explosion-proof fence for a car bomb,

[0040] Including step 1. Use the continuous roller shutter aluminum alloy fence as a bracket to surround large suspicious explosives,

[0041] Step 2. Surround the explosion-proof fence of the car bomb on the outside of the above-mentioned aluminum alloy inner bracket. According to the TNT explosive equivalent, it can surround the multi-layer explosion-proof fence, and each fence is connected through the buckle interface at its respective end.

[0042] Step 3. Bind with four high-performance fiber tapes on the outermost layer, and the high-performance fiber tapes are evenly distributed.

Abstract

The invention provides a car bomb explosion proof fence used for large quantities of explosive substances and large-size explosive substances and a use method thereof for preventing that the explosion of a car bomb or an irregular large-size suspected object damages surrounding people and environment. The width of the car bomb explosion proof fence is at least 1.8m, and the length is at least 20m. The car bomb explosion proof fence is formed by overlying at least 20 layers of high-performance fiber composite materials and sewing in a Z-shaped way, wherein high-performance fibers are preferable for high-strength high-modulus ultrahigh molecular weight polyethylene fibers. Both tail ends of the car bomb explosion proof fence are respectively provided with a connecting device such as a hole punching connecting device. When in use, a rigid inner bracket is used for enclosing the suspected object firstly, then the fence is wrapped and wound outside the inner bracket, and finally, the fence is bound by using the high-performance fibers.

Description

technical field [0001] The present invention relates to an explosion-proof device for preventing explosions from causing damage to personnel in the surrounding environment; furthermore, it relates to an explosion-proof fence for automobile bombs based on high-strength and high-modulus polyethylene fiber non-woven fabric composite material and its application method . Background technique [0002] Existing explosion-proof blanket is a kind of high-performance fiber composite material, the explosion-proof equipment that a kind of explosion-proof cover blanket and explosion-proof fence that are processed through special process are used in combination. In terms of hardness, it is divided into two types: soft body and hard body, and in terms of specifications, it is divided into two types: 1.2×1.2m and 1.6×1.6m. It is composed of explosion-proof fence and explosion-proof blanket, and the explosion-proof fence is 0.3×0.4m. When in use, first cover the suspected explosives with ...
